Ronaldo scored 69 goals in 59 games in 2013 while Messi topped 40 in far less matches. Despite the off-year, Martino asserts that Messi's body of work has been more compelling over the last few years.

"But the winner over one year is one thing, and a different thing is the best player in the world -- we have him here," he stated. "What he wants is for things to go well at Barcelona, and then with Argentina. From there the Ballon d'Or will be evaluated. But he is thinking first about being a decisive player for his club and country."

Martino's response is not surprising considering he coaches Messi at Barcelona.

Both superstars are likely to compete for the Ballon d'Or in 2014 but they will have more competition from the likes of Luis Suarez and Neymar among others. The World Cup will also have a major influence on the award, which will likely help determine the winner. Messi's Argentina is considered a favorite for the competition while Ronaldo's Portugal will need to overcome a number of hurdles to win the tournament.
